IMPROVIEID APPARATUS FOR DRAWING TIRES FROM ENGINE vDRIVIN(ir-VIVIIEELS.

TO ALL WIIOM IT MAY CON CERN:

Be it knownthat I, WILLIAM I-I. BRYANT, of Chicago, have invented a new and useful Apparatus for Removing Tire from Wheels; and I do declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the accompanying drawings, making parthoi` this specification, in whichl Figure 1 is an inside view of a driving-wheel with the apparatus attached for use.

Figure 2, a reversed view ofthe same.

Figure 3, a side view of the apparatus attached to a wheel, ready to use.

Like letters refer to like parts in all the figures.

I'o enable others skilled in the art to make and use my invention, I proceed to describe its construction and operation.

My device is designed to be used chiefly for drawing tire from the driving-wheels of railroad engines.

Areprcsents the driving-wheel of an engine; B the tire upon such wheel. I make a frame somewhat larger than an ordinary driving-wheel, of the form shown in the drawings, having a suitable number Aof arms C C properly secured at the centre. As shown in the drawings, these arms and the whole frame are made of wrought iron, about four and a half inches wide, and one inch thick. The arms are not solid, but each arm has. two parts, a a, with a space about two inches wide between them, so that the apparatus can be adjusted to wheels of various sizes. These arms, which are the chief part of the frame, may be made of a continuous bar of iron, and may be secured and strengthened by riveting the same to a metal hoop oni-ing, b. AI find that four arms are sufficient inordinary cases, though I do not confine myself to that number. The supports e, at one end, are four inches wide, seven inches long, and three-fourths of an inch thick. One end isdesigned to rest on the wheel A; the other end is narrower, so as to pass through between the two parts a a of, the arms C. At c is a shoulder, ou which the arm C rests. A pin,f, passing through the support e, holds it in place. The broad portion of the supports may be about seven inches long. The draw-bolts D are one and three-fourths inch bolts in size, provided with a screw-thread 'at one end, and with a projection or hook, m, at the other end With the draw-bolts D, I use a washer, c, cut away or recessed on one side, so as to it over the two parts a a of the arms C, and serving the purpose of preventing the draw-bolts from slipping. The supporting-bolts d are inch bolts in size, provided with a screw-thread at one end, andwith a head o n the other end, on .two sides oi the same, as shown in iig. 1. With these bolts I use an ordinary' washer, k. These supporting-bolts d are not an indispensable part of the apparatus; it can be used without them; but they are useful to steady the apparatus while in use, and toprovent the saule from tumbling down when the tire is drawn. In use, the supports e are placed, one between the two parts of the several arms, and fastened in place by the pinsf, at such distances from the centre that when placed on the wheel the supports will rest onrthe wheel just inside of the tire. When thus placed the frame is fastened in position by means of the supporting-bolts d, the headsof which catch against the arms j of the wheel. They are secured bymeans of the nuts The draw-bolts D are so placed that the projection or hook m catches the tire, when, by turning the nuts g, the tire can be'readily drawn oil. By

reversing the position of my apparatus, and placing it ou the opposite side of the wheel, Athe tire can be drawn on to the wheel. I l v Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is The apparatus for drawing tire from wheels, herein described, constructed and Aoperating substantially as herein set forth.

WM. H, BRYANT.
